SPRAYINGNGZZLE Application filed may 4i,

To all whom it mai/concern:

Be it known that I, MELVIN A. BARNES, a citizen vof the United States, residing at Elmira, in the county of Chemung and State of New York, have invented certain new and useful Improvements in Spraying-Nozzles,

ol" whichthe following is a specification.

This invention relates to improvements in nozzles employed for spraying trees, plants, shrubbery, or the like, with liquid insecticides or other solutions; and my object is to provide a simple 'and effective spraying nozzle., which, when in use, may be readily manipulated to clear the passageways therethrough from accumulations or depositsvof sediment, coagulations, etc., contained in the liquid solutions.

l attain my object by constructing the nozzles inthe manner illustrated in the accompanying drawings; in which- Figure 1 represents a complete nozzle, in side elevation; Fig. 2, a vertical section thereof; Fig. 3, a detail showing a spring coil employed in the nozzle; Fig. e, a transverse section on the line a-a in Fig. 2; Fig. 5, a vertical section of a different form of the nozzle and Fig. 6, a transverse section thereof on line b-b in Fig. 5.

Like numerals indicate like parts in the several views.

The nozzle as shown in Figs. i to 4 consists of a spindle l, provided at one end with a coupling 2, of hexagonal forni, by which to connect the nozzle with a spraying tube or hose. This spindle passes into the interior of a barrel 3, through a reduced opening at one end of said barrel, the' spindle and barrel at this point having a sliding iit so that the spindle will be longitudinally movable within the barrel. The opposite or outer end of the barrel is closed by a screw cap 4; said screw cap being knurled around its outer peri hery, and the barrel being made preferab y of hexagonal form to facilitate the application and removal of the cap.

The spindle is spaced'from the inner walls of the barrel, thereby providing an annular space 5, which is terminated at the inward end by a beveled seat 6, engaged bly the enlargement 7 upon the' s ind e, w ereby a liquid tight joint is former between the spindle and the barrel when the spraying liquid This enlargement 7 is preferably formed with a right angled edge Where it engages the seat 6, in order to insure a perfect engagement with Specification of Letters Patent.

the seat, since this right rangled edge will cut through sediment or the like deposited u on the seat, where la beveled seating su ace would be held away from the seat by said deposits.

The projecting end of the spindle is made leading from the coupling 2 to the cross bore 8, positioned on the inward side of the enlargement 7, so as to deliver liquid passing through the spindle into the space 5. ln the annular space 5 I place a spiral s ring 9,

Widthas the space, said spring resting upon the enlargement 7 at one end and against the cap 4 at the other end, and forming a spiral passageway around the'spindle from t e inlet duct 8 to the outer end ofthe barrel, whereby the liquid is given a swirling motion so that, as it issues Vfrom the central discharge oriice l() inthe cap, it Will spray out in all directions.

At the end of the spindle is a pin 'il of the same diameter as the orilice l0, which pin is adapted to be pushed-.through said oriiice to with reference to the barrel. The cap is made flat on its interior surface, and the end ofthe spindle surrounding the pin 1l is also a the spindle is pushed against the cap it will act to crush and disintegrate accumulations of sediment, etc., .within the nozzle, so that suoli deposits may pass out lthrough the discharge orifice. Furthermore, the coils ofthe spring 9 are so spaced apart that, when corn-V pressed by the outward travel of the spindle, sediment or other deposits contained Within the assageways between the coils will be crus led and broken up to such an 'extent that they will also pass out through the discharge orifice, whenfthe parts of the nozzle assume their normal position. This spiral spring, therefore, serves three purposes; tiret, as a crusher, to break up and disintegrate sedimentary deposits accumulating in the the liquid as it passes through the nozzle,l to produce the spraying effect; and third, as a guide for thespindle within the barrel. Under usual pressures, the liquid pressure alone in the barrel acting u on the enlargement 7 will be sufficient to 4old said enlargement upon the seat 6 to prevent leakage around the projecting end of the spindle; andftherehollow, by prov1ding it with a central bore formed preferably with flat coils of t esame clear it from obstructions, when a longitu-- dinal movement is imparted to the spindle flat surface of considerable area, so that whennozzle; second, to give the swirling motion tollt" fore, the spring is not required for thispurpassa es cleared.

In lgs. 5 and 6,-I have shown my invention as applied to another form of, nozzle, in which barrel 3IL is provided with 4a lateral offset, to receive the coupling, having an inlet duct 8a, the spindle 1a in this case being lmade solid and projecting a short distance beyond the point Where it passes out through In all otherrespects the construction and arran ethe opening at the end of the barrel.

ment of parts is the same as that before escribed. In operating this nozzle, to clear from sedimentary deposits,.' the end of the spindle 1EL is laced against a limb, or other stationary o` ject, and the barrel pressed toward the spindle, thereby causing the spindle to travel outwardly to compress the spring and project the pin'gll through orifice 10.

' I have thus shown my invention as ap-f It Will be readlied to two forms of nozzle.

l ily understood, however, that other forms 'and arrangements of the device may be conl structed Without departing from the spirit of motion, 'a spiral spring positioned between my invention.

What I clalm and desire to secure by Lettersl Patent sf 1. A spraying nozzle comprising a barrel hayinga reducedopening at one end and a cap at the other end provided-With a'disf charge orifice, a spindle movable longitudi-- nally Within thebarrel'and spaced from the inn'er walls thereof, said spindle passing out throughsaid o ening and having an en argement Within t e barrel to limit the outward I discharge orifice.

the cap and said enlargement in the space'I surrounding the spindle, the coils of said spring being of the same annular'width as the space and forming a compressible spiral `passageway therethrough, and a supply uct leading into said space.

2. A spraying nozzle comprising a barrel having a cap at one end provided with a discharge orifice, a spindlemovable 'longitudinally within the barrel and s ac ed from the inner walls thereof, said spind e having an'enlar ement on its )eri hery within the barrel,

a spiral spring avmg flattened coils surrounding the s indle 1n the space between the cap and sai enlargement, said coils being v of the sameannular width as the s ace, a supply duct leading Vto said space, an means for actuatin the spindle to compress the spring Where y lsolid particles lodging in said s ace will be disintegrated sufficiently to pass tlirou h the discharge orifice.

3. spraying nozzle comprising a barrel having -a cap at one end provided with a dis.

charge orifice, a spindle movable longitudinally Within the barrel and s aced from the inner walls thereof, said spin le being provided witha pin at one end ada ted to pass through the discharge orifice an having an enlarge-1 ment on its periphery Within the barrel, a spiral spring surrounding the spindle in the space between the cap and said enlargement, t e coils of said spring being of the same annular Width as the space, a supply duct leading to. said space, and means4 for actuating the spindle to compress the spring and prov ject the 'end 'of the spindle against the cap with the pin proj ectin through the discharge oriice, whereby soli particles lodgin 1n the space around. and over the spindle Wi l be disintegrated sufficiently to pass through the In testimony whereof I- have afliXed my signature, in presence of two witnesses.
